Spiroxamine (Prosper®) permit for Barley powdery mildew in WA, valid 1 April 2013 to 31 March 2016 http://permits.apvma.gov.au/PER14012.PDF
Fungicide resistance warning: fungicide resistance compromises control of barley powdery mildew by flutriafol, tebuconazole and triadimefon based fungicides – these fungicides provide variable and often poor levels of control and may promote further mutations of the powdery mildew fungus. In powdery mildew prone areas, use another registered fungicide instead. Where possible it is best to use the currently effective fungicide actives only once per season to reduce selection pressure on the powdery mildew fungus. For further information see the DAFWA website https://www.agric.wa.gov.au/barley/management-barley-powdery-mildew-2015-fungicide-resistance .
Procure® is registered only for spot type net blotch in barley and none of the other diseases.
Read labels of fungicides with active ingredient Epoxiconazole 125g/L clearly as registrations vary, some are not registered for scald, powdery mildew or net-type net blotch
Read labels of fungicides with active ingredient Propiconazole 250g/Lclearly as registrations and rates vary, many are not registered for leaf rust or net-type net blotch.
